No, you're not having a fever dream: The psychedelic opening actually does feature a rainbow-silhouetted samba number, lots of multi-colored dots, and three men walking with canes to the tune of "Three Blind Mice"
The three blind men wander the streets of Kingston Jamaica.
The men stop at the Queen's Club, and they seem to realize where they are even though the sign is not in Braille.
At the Queen's Club—not a drag queen bar—four old white men gamble at cards.
One of the men leaves the card game and drops a coin into the blind man's tin cup.
But he's not blind after all. He has quite good eyesight, in fact, which he uses to shoot the man dead, load him into the back of a car, and speed away. Whoa.
A woman talks into a secret radio hidden behind a fake bookshelf.
The three blind men break in and shoot her dead, too.
They rifle through her files and recover a document labeled DOCTOR NO. Was it under "D" for Doctor, or "N" for No?
